Arc Studio Pro vs Pendraic

Arc Studio Pro is screenwriting software for drafting and managing scripts on Mac, Windows, iPadOS, iOS, and browsers. Its writing tools include industry formatting, Focus mode, timed sprints, notes, and outlining. Users can work offline, while automatic draft history lets them recover deleted text. Encryption and automatic backups protect work on devices and in the cloud. The Free plan includes up to two scripts and PDF export with a watermark; the free writing experience can begin without a credit card, and each account includes a free 7-day Pro trial. Free is free, billed annually. Essentials costs $69 a year and includes unlimited scripts, advanced formatting, desktop and mobile apps, and PDF export. Pro costs $99 a year and adds features including outlining, revision management, feedback links, and two collaborators. Collaboration works on Free, but inviting collaborators requires a subscription. The product is published by Arc Studio Labs, Inc., headquartered in Wilmington, Delaware, USA.

Pendraic is a long-form fiction writing tool for keeping a book's characters, world, voice and story details together. The editor provides prose, outline and arcs views, with optional panels for character lookups, voice consistency, beats and unresolved threads. Planning and revision are organized into eight areas: Promise, Engine, Nexus, Dynamics, Registry, Anchors, Iterations and Closure. Its World Builder links maps, family trees, calendars, languages, timelines and encyclopedia entries to the prose. Listed AI options include Claude, ChatGPT, Gemini, Grok and OpenRouter, using either a user's account or a Pendraic Managed AI wallet. When a user starts an AI generation pass, the prompt and needed context go to the chosen provider under that provider's terms. Pendraic says saved files are encrypted in transit and at rest, and that it does not train models on users' writing or sell their content. The Free plan supports up to three active books and includes Word, Markdown and plain-text exports. Pendraic runs on macOS, Windows and the web; paid plans start at $14.99/mo.
